Nyob rau hauv kev tsim kho ntawm cov tsev lag luam, txias saw logistics, thiab kev cob qhia huv, kev ua haujlwm ntawm cov khoom siv rwb thaiv tsev ncaj qha txiav txim siab txog kev tswj hwm ib puag ncig ntawm qhov project cov nqi khiav lag luam. Yuav ua li cas xaiv cov khoom siv tau zoo, txhim khu kev qha, thiab kev siv nyiaj txiag tau dhau los ua qhov teeb meem tseem ceeb rau txhua qhov kev txiav txim siab engineering-tus tsim.
PU Sandwich Vaj Huam Sib Luag boasts zoo heev thermal rwb thaiv tsev kev ua tau zoo thiab tau lees paub thoob ntiaj teb raws li ib qho ntawm cov khoom uas muaj qhov qis tshaj thermal conductivity thiab zoo tshaj rwb thaiv tsev nyhuv ntawm tag nrho cov ntaub ntawv rwb thaiv tsev tam sim no. Kab lus no yuav txheeb xyuas qhov tseem ceeb ntawm kev ua haujlwm thermal rwb thaiv tsev ntawm PU Sandwich Vaj Huam Sib Luag.
I. Qhov taw qhia tseem ceeb ntawm thermal rwb thaiv tsev kev ua tau zoo: Thermal conductivity
Thermal conductivity yog lub cev kom muaj nuj nqis uas ntsuas lub peev xwm ntawm kev hloov hluav taws xob. Qhov tsawg dua tus nqi, qhov zoo dua thermal rwb thaiv tsev kev ua tau zoo ntawm cov khoom, thiab nws yog qhov nyuaj dua rau cov cua sov kom dhau los ntawm cov khoom siv. Hauv lub tsev lub hnab ntawv, cov ntaub ntawv uas muaj cov thermal conductivity qis dua tuaj yeem ua tiav cov thermal rwb thaiv tsev zoo tib yam nrog cov ntaub ntawv nyias, lossis ua tiav lub zog zoo dua - txuag cov teebmeem nrog tib lub thickness ntawm cov ntaub ntawv.
II. Technical txoj cai ntawm thermal rwb thaiv tsev kev ua tau zoo
1. Cov qauv microscopic: Siab kaw-cov xov tooj ntawm tes ua npuas ncauj
Cov khoom tseem ceeb ntawm PU Sandwich Vaj Huam Sib Luag yog nruj polyurethane ua npuas ncauj, uas yog siab -molecular polymer nrog kaw {{1} cell qauv. Lub kaw- cell qauv txhais tau hais tias cov npuas hauv cov npuas dej yog ywj siab thiab tsis txuas nrog, tsim cov kab kaw micro-chamber.
- High kaw-tus nqi ntawm tes: Cov hlwb kaw no muaj cov khoom ua npuas ncauj nrog cov thermal conductivity tsawg heev, uas tsis pub dawb- cua ntws.
- Gas convection yog suppressed: Cov npuas sab hauv yog ywj siab, yog li cov cua sov tsis tuaj yeem hloov mus rau hauv cov khoom los ntawm cov pa roj convection, txo cov thermal conduction efficiency.
- Radiant tshav kub yog thaiv: Cov phab ntsa ntawm tes ntawm cov khoom ua npuas ncauj muaj qee qhov kev xav thiab thaiv cov nyhuv ntawm cov hluav taws xob hluav taws xob.
Nws yog qhov tseeb qhov tshwj xeeb microscopic qauv uas paub tseeb "tag nrho-band" rwb thaiv tsev.
2. Cov khoom tseem ceeb: Qhov zoo ntawm cov thermosetting yas
Polyurethane rigid ua npuas ncauj belongs rau thermosetting yas. Nws yuav tsis yaj thiab ntws thaum cua sov, tab sis tuaj yeem tswj kev ruaj ntseg thiab tsim cov txheej txheem carbonization ntawm qhov kub thiab txias. Cov yam ntxwv no tsis yog tsuas yog ua rau PU Sandwich Vaj Huam Sib Luag muaj hluav taws kub, tab sis kuj ua kom ntseeg tau tias PU Sandwich Vaj Huam Sib Luag yuav tsis tawg vim qhov kub thiab txias hloov thaum lub sij hawm ntev - siv, yog li tswj kev ruaj ntseg ntawm nws cov kev ua tau zoo.
3. Ultra- tus nqi nqus dej tsawg
Ntau cov dej-cov ntaub ntawv nqus tau muaj qhov ua tau zoo hauv lub xeev qhuav, tab sis thaum lawv nqus dej thiab ntub dej, cov thermal conductivity yuav nce sai, yog li txo cov rwb thaiv tsev zoo heev. Txawm li cas los xij, PU Sandwich Panel muaj qhov zoo ntawm qhov no:
- Kev nqus dej tsawg heev: Cov dej nqus dej ntawm PU Sandwich Vaj Huam Sib Luag yog Tsawg dua lossis sib npaug li 0.5g / 100cm²
- Cov khoom siv hydrophobic: Polyurethane yog cov khoom siv hydrophobic thiab yuav tsis ua kom cov thermal conductivity vim dej nqus thiab dampness.
Cov txiaj ntsig no tseem txhais tau hais tias txawm tias nyob hauv ib puag ncig ntub, kev ua haujlwm thermal ntawm PU Sandwich Vaj Huam Sib Luag tuaj yeem nyob ruaj khov, thiab cov tuab sib xws tuaj yeem xaiv tau raws li qhov xav tau sib txawv, uas tuaj yeem ua tau raws li cov kev cai rwb thaiv tsev thaum tswj cov khoom siv.
III. Cov nqi siv tau coj los ntawm kev ua haujlwm thermal rwb thaiv tsev
1. Kev txo nqi hluav taws xob tseem ceeb
Rau cov tsev uas nruab nrog kub tswj tshuab, thermal rwb thaiv tsev kev ua tau zoo ntawm cov txheej txheem enclosure tuaj yeem txiav txim ncaj qha rau kev khiav hauj lwm ntawm qhov kub thiab txias.
- Cov xwm txheej txias txias: Cov txiaj ntsig zoo rwb thaiv tsev feem ntau txhais tau hais tias tus naj npawb ntawm lub sijhawm lub tshuab tub yees pib raug txo, lub sijhawm ua haujlwm luv luv, thiab cov nqi hluav taws xob txo.
- Cov nroj tsuag muaj: PU Sandwich Vaj Huam Sib Luag muab cov rwb thaiv tsev rau lub caij ntuj sov thiab lub caij ntuj no cua sov, txo kev siv lub zog ntawm cov cua txias thiab cua sov, thiab txo qis - cov nqi khiav haujlwm ntev.
2. Txo lub tsev tuab thiab ua kom thaj chaw siv tau
PU Sandwich Vaj Huam Sib Luag muaj cov thermal conductivity tsawg heev, yog li nyob rau hauv qhov kev ua tiav ntawm kev ua tiav tib lub rwb thaiv tsev, cov khoom siv thickness yuav tsum tsawg dua li lwm cov ntaub ntawv.
3. Ntev -lub sij hawm ruaj khov thermal rwb thaiv tsev kev ua tau zoo
Vim nws qhov siab kaw -cov xov tooj ntawm tes thiab qhov nqus dej tsawg, qhov kev ua haujlwm thermal rwb thaiv tsev ntawm PU Sandwich Panel muaj kev ruaj ntseg zoo heev. Raws li kev siv ib txwm muaj, cov nyhuv rwb thaiv tsev tuaj yeem kav ntev txog 30 xyoo yam tsis muaj qhov cuam tshuam loj. Nws tsis yog ib qho - lub sij hawm noj tab sis ib tug ntev - khoom vaj khoom tsev.
4. Txo cov cuab yeej siv peev
Qhov zoo tshaj plaws thermal rwb thaiv tsev kev ua tau zoo ntawm PU Sandwich Vaj Huam Sib Luag feem ntau txhais tau hais tias cov khoom siv hluav taws xob me me tuaj yeem raug xaiv, txo cov khoom siv peev. Nyob rau tib lub sij hawm, nws kuj txo cov kev khiav hauj lwm load ntawm cov khoom thiab ncua nws cov kev pab cuam lub neej, ntxiv txo tus nqi lifecycle.
IV. Kev Xaiv Qhia rau PU Sandwich Vaj Huam Sib Luag
1. Txheeb xyuas daim ntawv qhia txog kev ntsuas thermal conductivity
Xav kom tus neeg muag khoom muab daim ntawv pov thawj thermal conductivity test report, paub meej tias tus nqi qis dua 0.024W / m`K thiab ua raws li cov khoom siv tiag tiag.
2. Ua tib zoo saib rau qhov kaw - tus nqi ntawm tes thiab tus nqi nqus dej
Ob qhov txiaj ntsig no tuaj yeem cuam tshuam ncaj qha rau lub sijhawm ntev - kev ruaj ntseg ntawm kev ua haujlwm rwb thaiv tsev.
3. Xaiv cov khoom tseem ceeb uas tsim nyog
Xaiv cov khoom siv ntom ntom uas tsim nyog raws li qhov xav tau ntawm cov rwb thaiv tsev sib txawv, lub zog, thauj khoom -cov kev cai bearing, thiab lwm yam.
